Permissible torque
The connection box housing is made of plastic. Therefore, the mounting hole threads
cannot handle the same amount of stress as a comparable metallic housing. Only tighten
the screws with the permitted torque of 0.4 to 0.5 Nm.
If the screws are tightened more than 20 times, there is risk of damage to the threads.
Degree of protection not fulfilled
Ensure that the seal belonging to the cover is present during assembly. When you have
finished working on the connections, check to make sure that the unused threaded cable
entry holes are fitted with rubber plugs. Otherwise degree of protection IP65 is not ensured.
